Which of the following statements shows the inverse property of addition?

a + (-a) = 0
a + 0 = a
1a = a
a + a = 2a

The answer is a + (-a) = 0

Step-by-step explanation:

The inverse property of the sum states that any number added with its opposite results in 0, that is, a positive integer added with its negative opposite integer is equal to 0.

So if in the equation "a + (-a) = 0 " we replace "a" with any number and "-a" with its opposite, we would have 0 as result. for example:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
